Romans 14:19-23
Let us therefore follow after the things which make for peace, and things wherewith one may edify another. For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence. It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak. Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth. And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
Romans 15:1-13
We then that are strong ought to bear the infirmities of the weak, and not to please ourselves. Let every one of us please his neighbour for his good to edification. For even Christ pleased not himself; but, as it is written, The reproaches of them that reproached thee fell on me. For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope. Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus: That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
Wherefore receive ye one another, as Christ also received us to the glory of God. Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers: And that the Gentiles might glorify God for his mercy; as it is written, For this cause I will confess to thee among the Gentiles, and sing unto thy name. And again he saith, Rejoice, ye Gentiles, with his people. And again, Praise the Lord, all ye Gentiles; and laud him, all ye people. And again, Esaias saith, There shall be a root of Jesse, and he that shall rise to reign over the Gentiles; in him shall the Gentiles trust. Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Ghost.
